Actually OnlineAuc is serialized when an AdaptiveLogisticRegression is
serialized. This is done to checkpoint a large incremental training
run. That serialized form is also used in some cases to deploy a
model to production or to do model diagnostics.

Someone remind me about why we use 'transient' in the code?
It has no meaning outside of java.io.Serializable, and customizing

But, I remember someone commented at one point that it has meaning
for
the GSON serialization mechanism. True?
If so, is there a sense of which classes that affects? since I see it
in classes I don't think would ever be serialized like OnlineAuc.
Yes, Gson will not serialize transient state. It's also a reasonable
way to indicate transient state that is not serialized by Writable.
See AbstractCluster for an example.
